Factor out g_main_context_init_pipe from g_main_context_new to initialize

Browse Source 
2002-08-06  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* glib/gmain.c: Factor out g_main_context_init_pipe from
	g_main_context_new to initialize the wakeup pipe of a
	context. Call that function from g_main_context_new if threads are
	initialized and for all contexts when threads are initialized
	in g_main_thread_init. (#86872)

	* gthread/gthread-impl.c: Call g_main_thread_init. (#86872)
